2014-06-26 · near Melville, Sweet Grass, Montana

Event narrative

Hail accumulated to 2 inches on the ground and was accompanied by 40 to 50 mph winds.

Wider weather episode

A mid/upper level trough and associated 40-50kt wind max moved across an increasingly unstable airmass across eastern Montana. Daytime heating and large scale ascent combined with a low-level east/southeast flow helped support storm updraft rotation which produced a few severe thunderstorms across the area.
